DANVIL ATTACHMENT.

SPECIFEECATION formingpart of Letters Patent No. 486,504., datedNovember 22, 1892.

Application filed February 1, 1892. $erial No. 419,975. (No model.)

To all whom it natty concern:

Be it known that I, GEORGE W. RICE, a citizen of the United States ofAmerica, residing at Des Moines, in'the county of Polk and State ofIowa, have invented a new and useful Anvil Attachment, of which thefollowing is a specification.

My object is to provide strong, durable, and convenient means whereby ahorseshoe may be held in position by foot-pressure, as required, to formcalks and clips thereon, to provide improved means for holding bolts,&c., while heads are being formed thereon.

My invention consists in the construction of an attachment to be appliedto the end of an anvil, an adjustable jaw adapted to be operated byfoot-power, and in the construction and combination of various swagingdevices adapted to be connected with or clamped between the said jawsfor the purpose of shaping horseshoes and forming heads on bolts,-

&c., as hereinafter set forth, pointed out in my claims, and illustratedin the accompanying drawings, in which Figure 1 is a side View of ananvil provided with my attachment. Figs. 2 and 3 are respectively endand top views of the same. Fig. 4 is a transverse sectional view throughthe line a; so of Fig. 3. Fig. 5 is a perspective view of a deviceadapted to be placed in an angular opening in one of the jaws to aid informing the clips of horseshoes, &c.; and Figs. 6 and 7 are perspectiveviews of the attachments adapted to aid in forming bolt-heads.

Referring to the accompanying drawings, the reference-letter Ais used todesignate an anvil.

B represents an attachment having an enlarged fiat top surface. Itslower extremity is adapted to rest upon the floor and its top to providea continuity of surface with the top of the anvil. Its one side isslightly beveled outward for convenience and also roughened to aid inclamping articles therein. In its approximate center is an angularopening B adapted to admit and securely retain mating projections from ametal block. Formed on the corners of its j aw-surface are two angularto one corner of the stationary-jaw portion and has its top edgessharpened and rounded, as clearly shown in the accompanying drawings.

The part B is preferably detachably connected with the anvil-supportingblock in the following manner: Two lugs D D, adapted to admit theupright portion of the partB be-' tween them and provided with angularopenings in the outer ends, are fixed to the side of the said block andtwo lugs D D are fixed to the side of the said block. hen it is desiredto secure the part B thereon,it is placed between the said lugs and thekey D driven through the angular openings in the lugs D D, having itsinner edge engaging the said part 13, thereby securely clamping ittherein.

F represents the movable jaw of the vise. It is provided with anenlarged top portion and a beveled and roughened side face injuxtaposition to the said fixed jaw, as required to mate therewith. Nearits central portion it is pivoted to the upright portion of thestationary jaw and the lower end is bent to overlap the side of the saidupright portion of the stationary jaw. Formed in the top face of themovable jaw is an angular cavity adapted to admit a block, and theset-screws F eX- tended through the sides of the said opening, providemeans whereby the block may be clamped therein. To operate the saidmovable jaw relative to the said stationary jaw by foot-pressure, I.provide the following mechanism:

H represents a lever having a treadle H formed on or fixed to its oneend. Near its other end is an opening adapted to serve as a bearing, andacam-shaped projection H is extended upward therefrom and adapted toengage the lower end of the movable jaw portion. This lever is pivotedto a perforated projection H, from the lower end portion of thestationary jaw. The said perforations are for the purpose of providingmeans for shifting the pivoted point of the said lever and therebyadjusting the distance of the said jaws relative to each other.

J represents a coil-spring connected with the outer end of the lever Hand with the bars of the part B, as required to normally hold thetreadle elevated. It will be obvious that the upper end of the movablejaw will normally incline outward by gravity, the top thereof being muchheavier than the bottom portion.

K represents a block adapted to enter the cavity formed in the top ofthe portion F. Its top surface is beveled from the side upward andpreferably at different angles.

When it is desired to form calks on a horseshoe, the shoeis placedbetween the jaws, having the part upon which the calk is to be formedextending upwardly above thejaws. The jaws are then clasped together byfootpressure, as before described, leaving the handsfree to form thecalks by bending them over the block and hammering the upper surfacethereof fiat. This, it will be seen, will produce sharpened calks, asthe block upon which they are formed is beveled.

L represents a block adapted to be placed on the opening B and inposition as indicated by dotted lines in Fig. 3. Its end extends to theedge of the jaw F and provides a continuity of surface with the face ofthe said jaw, so that when a toe-calk is being formed the top surface ofthe shoe may be kept from bending in either direction.

To form heads on bolts, I insert the part M (shown in Fig. 6) in theangular openings B B in the stationary jaw and the angle-iron M in thecavity in the movable jaw. I then clamp a bolt between their coincidingvertical grooves, so that its top end will project over the top surfaceof the parts M and M as required, to allow it to be shaped into a headby means of a hammer in a common way. The said grooves may vary innumber, as desired, and are preferably graduated in size to engage boltsof different diameters.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

. 1. An attachment for anvils, adapted to aid in forming calks onhorseshoes, comprisinga part resting on the floor-surface, detachablysecured to the anvil-block and providing a continuity of surface withthe top of the angular end of the anvil, a movable portion adapted to beoperated by foot-pressure, pivoted to the side of the aforesaid portion,the meeting edges of the said parts adapted for grasping articlesbetween them, a metal block having its top surface inclined at twodifferent angles and adapted to be detachably and reversibly connectedwith one of the said parts, and a block having a Hat end surface adaptedto be detachablyconnected with the other part to provide a continuity ofsurface with its end which is in proximity to the aforesaid jaw,substantially as set forth.

2. An attachment for anvils, adapted to aid in forming calks and clipson horseshoes, comprising a stationary jaw having a base adapted to reston the floor, an. upright portion detachably connected with thesupporting-block of the anvil and having a smooth top surface adapted toprovide a continuity of surface with the top of the anvil, a movable jawpivotaliy connected with the upright portion of the said fixed jaw,means for operating the said movable jaw by foot-pressure, an angularmetal block having its top surface inclined or beveled upwardly from thesides, detachably fixed in the said movable jaw, a metal block having asmooth end surface adapted to provide a continuity of surface with theinner edge of the fixed jaw, detachably connected with the said fixedjaw, and an extension adapted to aid in forming clips on a horseshoe,having its upper edge sharpened and rounded, fixed to one corner of thesaid fixed jaw, to operate substantially in the manner set forth, forthe purposes stated.

3. An attachment for anvils, comprising, the fixed jaw B, provided withthe openings B and B B the clip-forming attachment 0, fixed to ouecornerthereof, the lugs D D and D D fixed to the anvil-block, the key D themovable jaw F, the set-screws F F in the sides thereof, the lever I-I,having the treadle H and cam H pivoted to a projection H, extending fromthe side of the upright portion of the part B, the coil-spring J, theblock K, and the block L, all constructed and combined substantially inthe manner set forth, for the purposes stated.
